scope:

This part of ISO 3691 gives safety requirements and the meansfor their verification for the following types of self-propelledindustrial trucks (hereafter referred to as trucks), as defined inISO 5053: a) industrial counterbalanced trucks; b) reach truckswith retractable mast or retractable fork arm carriage; c) straddletrucks; d) pallet-stacking trucks; e) high-lift platform trucks; f)trucks with elevating operator position up to 1 200 mm; g)side-loading trucks (one side only); h) lateral-stacking trucks(both sides), and lateral- and front-stacking trucks; i) pallettrucks; j) bidirectional and multidirectional trucks; k) tractorswith a drawbar pull up to and including 20 000 N; l) rough-terraincounterbalanced trucks; m) industrial trucks powered by battery,diesel, gasoline or LPG (liquefied petroleum gas). NOTE 1 Truckspowered by CNG (compressed natural gas) are not dealt with. It isintended that CNG and other power sources be addressed in futurerevisions of this part of ISO 3691. For trucks with an elevatingoperator position of more than 1 200 mm and/or trucks designed totravel with an elevated load of more than 1 200 mm, this part ofISO 3691 is intended to be used in conjunction with ISO 3691-3.NOTE 2 ISO 3691-3 is not applicable to counterbalanced fork lifttrucks or trucks intended for container handling. NOTE 3 Somelow-level order pickers with an elevating operator's position up toand including 1 200 mm lift height can be equipped with anadditional lifting device to lift the load to a maximum lift heightof 1 800 mm. This part of ISO 3691 is not applicable toself-propelled variable-reach trucks, driverless trucks or burdencarriers, which are covered in ISO 3691-2, ISO 3691-4 and ISO3691-6, respectively. It is not applicable to industrial trucksoperating in severe conditions (e.g. extreme climates, freezerapplications, hazardous environments), where special precautionscan be necessary. Regional requirements, additional to therequirements given in this part of ISO 3691, are addressed inISO/TS 3691-7 and ISO/TS 3691-8. This part of ISO 3691 deals withall significant hazards, hazardous situations or hazardous events,as listed in Annex B, with the exception of the following, relevantto the applicable machines when used as intended and underconditions of misuse which are reasonably foreseeable by themanufacturer. It does not establish requirements for hazards thatcan occur ? during construction, ? when handling suspended loadsthat can swing freely, ? when using trucks on public roads, ? whenoperating in potentially explosive atmospheres, ? when using trucksin very narrow aisles with clearance of less than 500 mm to theracks, ? arising from a non-ergonomic body attitude when drivingsit-on trucks, load trailing, ? during travelling with unladentrucks having a rated capacity of more than 10 000 kg, due tovisibility concerns, ? due to overload. NOTE 4 For the purposes ofthis part of ISO 3691, fork arms, load platforms and integratedattachments are considered to be parts of the industrial truck.Attachments mounted on the load carrier or on the fork arms whichare removable by the user are not considered to be part of theindustrial truck. Requirements for attachments are given in theappropriate clauses.
